Patent

CA 2318478

The device is an articulated cam (10) with an at least partially rotatable cam arm (12) for mounting a vertical traveling industrial door (100), constructed from a series of hinged solid panels (102), to a guide track (110). The cam arm (12) has a threshold force required for rotation as the cam arm (12) includes a dimple (56) which is engaged by a spring-biased nipple (40). When this threshold force occurs due to impact on the door (100), the cam arm (12) rotates and the articulated cam (10) and the door (100) break away from the guide track (110).

Cette invention concerne une came articulée (10) qui comprend un bras (12) de came capable d'effectuer une rotation au moins partielle. Ce bras de came permet de monter une porte verticale, coulissante et à vocation industrielle (100) sur une piste de guidage (110), laquelle porte se compose d'une série de panneaux solides articulés (102). Une certaine force seuil doit être exercée pour faire tourner le bras (12) de came, lequel bras comporte un logement (56) dans lequel pénètre un téton (40) poussé par un ressort. Lorsque la force seuil est atteinte à la suite d'un impact sur la porte (100), le bras (12) de came entre en rotation tandis que la came articulée (10) et que la porte (100) se séparent de la piste de guidage (110).
